Change of Base. Sometimes we will be faced with logarithmic or exponential are not the same. Being able to change from one base to these situations. Let's have a look at the change of base functions. Let's try and prove the change of base formula.
The Change of Base formula is also useful for simplifying expressions involving logarithms of the same number to different bases, as the next 2 examples show. Example 6 Simplify 1 log4 5 + 1 log3 5. We know that 1 log4 5 = log5 4, and likewise 1 log3 5 = log5 3. Once everything is expressed to the same base we can use the properties of ...

Logarithms. The mathematics of logarithms and exponentials occurs naturally in many branches of science. It is very important in solving problems related to growth and decay. The growth and decay may be that of a plant or a population, a crystalline structure or money in the bank.
Consider the expression 16 = 24. Remember that 2 is the base, and 4 is the power. An alternative, yet equivalent, way of writing this expression is log 2 16 = 4. This is stated as ‘log to base 2 of 16 equals 4’. We see that the logarithm is the same as the power or index in the original expression.
